Specifically, 'size'\nwill point to 'tmp' variable before the latter had a chance to be\nassigned any value.\n\nPlay it safe and init 'tmp' with 0, thus ensuring that\nradeon_vce_cs_reloc() will catch an early error in cases like these.\n\nFound by Linux Verification Center (linuxtesting.org) with static\nanalysis tool SVACE.\n\n(cherry picked from commit 2d52de55f9ee7aaee0e09ac443f77855989c6b68)"
